Magnetism Question 288
Question: The basic magnetization curve for a ferromagnetic material is shown in figure. Then, the value of relative permeability is highest for the point
Options:
A) P
B) Q
C) R
D) S
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ B={\mu _{0}}{\mu _{r}}H\Rightarrow {\mu _{r}}\propto \frac{B}{H} $ = slope of B-H curve According to the given graph, slope of the graph is highest at point Q.
